Daniel Jasper b812e323fa clang-format: Make braced list formatting more consistent. 
Before:
  Aaaa aaaaaaaaaaa{
      {
       a, // +1 indent weird.
       b, // trailing comma signals one per line.
      },  // trailing comma signals one per line.
  };

After:
  Aaaa aaaaaaaaaaa{
      {
          a, // better!?
          b, // trailing comma signals one per line.
      },     // trailing comma signals one per line.
  };

Interesting that this apparently was entirely untested :-(.

Daniel Jasper 29d39d54e7 clang-format: Correctly mark preprocessor lines in child blocks. 
This prevents contracting:
  auto lambda = []() {
    int a = 2
  #if A
            + 2
  #endif
        ;
  };

into:
  auto lambda = []() { int a = 2
  #if A + 2
  #endif ; };

Which is obviously BAD.

This fixes llvm.org/PR22496.

Nico Weber 33381f5e0b clang-format: Format Objective-C try blocks like all the other try blocks. 
Before:

  @try {
    // ...
  }
  @finally {
    // ...
  }

Now:

  @try {
    // ...
  } @finally {
    // ...
  }

This is consistent with how we format C++ try blocks and SEH try blocks.
clang-format not doing this before was an implementation oversight.

This is dependent on BraceBreakingStyle.  The snippet above is with the
Attach style.  Style Stroustrip for example still results in the "Before:"
snippet, which makes sense since other blocks (try, else) break after '}' too.

 2015-02-05 11:05:31 +00:00
Nico Weber fac2371be3 clang-format: Add support for SEH __try / __except / __finally blocks. 
This lets clang-format format

    __try {
    } __except(0) {
    }

and

    __try {
    } __finally {
    }

correctly. __try and __finally are keywords if `LangOpts.MicrosoftExt` is set,
so this turns this on.  This also enables a few other keywords, but it
shouldn't overly perturb regular clang-format operation.  __except is a
context-sensitive keyword, so `AdditionalKeywords` needs to be passed around to
a few more places.

Fixes PR22321.

Nico Weber ece3d3c26e clang-format: Let Chromium use the Google default for AlignTrailingComments. 
r225141 changed the defaults of AllowShortIfStatementsOnASingleLine and
AlignTrailingComments for Google style and added explicit overrides for
Chromium style to undo these changes.  For AllowShortIfStatementsOnASingleLine
that's good as the Android style guide (which Chromium uses for Java) explicitly
permits single-line ifs. But it's silent on trailing comments, to it makes
sense for Chromium style to just follow Google style.

Roman Kashitsyn 650ecb53ca Fix bug 20892 - clang-format does not handle C-style comments 
Summary:
http://llvm.org/bugs/show_bug.cgi?id=20892

Add support of C-style formatting enabling/disabling directives. Now the following two styles are supported:

  // clang-format on
  /* clang-format on */

The flexibility in comments (support of extra spaces and/or slashes, etc.) is deliberately avoided to simplify search in large code bases.

On a single line:

Not on a single line:

Daniel Jasper 23376259c0 clang-format: [JS] Support regex literals with trailing escaped slash. 
Before:
  var regex = / a\//; int i;

After:
  var regex = /a\//;

This required pushing the Lexer into its wrapper class and generating a
new one in this specific case. Otherwise, the sequence get lexed as a
//-comment. This is hacky, but I don't know a better way (short of
supporting regex literals in the Lexer).

Pushing the Lexer down seems to make all the call sites simpler.

Summary:
http://llvm.org/bugs/show_bug.cgi?id=20587

Added K&R style. It could be enabled by the following option:

```
BreakBeforeBraces: KernighanRitchie
```

This style is like `Attach`, but break *only* before function
declarations.

As I can see, no additional logic required to support this style, any
style different from other styles automagically satisfies K&R.
